SIDE BEARING FOR RAILWAY-CARS.

Railway-Cars; and I do hereby declare theV Yfollowing to he a full, clear, and exactde- `scription of the invention, such as will 0u-- able others skilled in the art to which it appertains to make and use the same.

My present invention has for object to provide an improved Side bearing for railway cars and, to this end, it consists of the novel devices and combinations of devices hereinafter described `and`delined in the claim.

In thel accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views'.

.leferring' to the drawings, Figure 1 is-a, plan view of the improved side bearing,

somepauts being removed: FiO'. :2 is a. viewin inneb sidb elevatior of the said sidexbearidg,so1ne "parts being removed.; Fig.' 3 is a vertical section taken approximately on the line .f/.t/f of Fig. l, some parts being shown in full; and F ig. 4 is a fragmentary view in outer 'side elevation showing a por.

tion of the side bearing casting.

The iml'irovcd side bearing comprises a i V`cast roller .supporting bearing or box, 1, pref# `erably of cast steel. The sides and base of this box are flanged and ribbed for the. sake of strength and lightness, and theside flanges are formed with axially alined pairs of inner and outer hub oi sleeve-likeA axleA seats 2 and respectively, in which are normally1 seated heavy axles 4, upon which heavy bearing rollers are loosely journaled. the said rollers being held against endwise movement b v the cooperating hubs 2 and T he axes of the axles 4.are pret'-` erably arranged so that they diverge or radiate from the axis of the car center bearing.

'vention is found in the construction which ides for the application of the axles fr fn# -ng hubs and in the removal Specific-ation of Letters Patent.

Application leli'Apri1k22, 1910. `Serial No. 558,912.

The feature of novelty in thefpresent inthis purpose, the inner hubs 2 vare madevround so that they will quite closely llt the. ends of the axles, and the seats in the hubs 3 are vertically elongated sol that, when the axles are in position, lock pifns or heavy cotters 6 may be passed throughfhorizontal -perforations that transversely intersect the upper portions of the said elongated seats 3, The hubs Zand 3, at vthe lower.. tion's of their outer extremities, are provi ed with.' stop, anges 7 and 8 that hold the 'axles 4,v

against endwise movements@Y 1 lVhen the plus or cotters `6 are removed,

theouter ends of the axles 4 may be. raised in the seats 3, and' thesev seats are of such vertical dimensions that when-the said axles Vare vraised they may be moved endwiseiover the tops of the stop flanges 8. This, as is evident, makes it an .easy matter to ap- 'ply the axles in working positions in the coperating hubs 2 and 3, or to remove the same therefrom when the pins or cotters 6 are removed. `When the axles are in workl ing position vand the pins or cot-ters 6 are applied, the axles are, as is evident, securely locked in'working positions and, furthermore, the endwise thrust on' the axles will be taken by the stop flanges .7 and 8; and the 'pins o r cotters 6 have only to prevent jumping of the outer ends of the axles. y()wing to the fact that each sleeve y2 is open at its outer end and freely accessible, the finger may be inserted therethrough to push the axle 4 endwise out f the transversely elongated sleeve 3 when said axle is/raised over the stop flange 8. r

The parts of this improved side bearing may be very-quickly assembled or taken apart.v The construction, furthermore, pro- Patented Nov. 7, 1911( vides, at' comparatively small cost, a very v strong, durable'and generally efficient side bearmg 'for railway cars.

The term lockfor stop flange, as ap. plied to the flanges orY outer extremities of the axle seats of-v the hubs 2 and 3 is used ina liberal sense to include stop devices for normally preventing ndwise movement of the axle.

That I claim is:

A side bearing for cars, comprising a hoxlike castingrhaving bearing hubs \v1th axially alined sleevelike seats and stops at tlr- 2 1,oo7,7es

outer extremities of said seats, an axle tnormally holding said axle in working positlng said sleevelike seats, a roller` removably tion. mounted on snld axle, one of the axle seats In testimon whereof I aix my signature being vertically elongated so that the said in presence o two Witnesses.
